Choose the the option that best describe how cytokinesis works in animal and plant cells.
1. Animal cells: A cell plate forms along the equator of the parent cell and a new cell wall and plasma membrane form on either side of the plate.
2. Animal cells: The plasma membrane pinches in along the parent cell's equator to form two daughter cells.
3. Plant cell: The plasma membrane pinches in along the parent cell's equator to form two daughter cells.

Answer is Option "1"

Explanation:

In animals, cell division occurs when a band of cytoskeletal strands called the contractile ring contracts internal and squeezes the phone in two, a procedure called contractile cytokinesis. The space created as the ring contracts internal is known as the cleavage wrinkle. Creature cells can be squeezed in two because they're relatively soft and squishyPlant cells are much stiffer than animal cells; they're encompassed by an inflexible cell divider and have high inside weight. Along these lines, plant cells separate in two by building another structure down the center of the cell. This structure, known as the cell plate, is comprised of plasma layer and cell wall segments conveyed in vesicles, and it parcels the cell in two

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite   shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
